### MP-143 Servo chassis power supply fault

There is a +60v DC power supply failure on the servo control unit (SCU) chassis. It could be caused by a blown fuse in the 60v power supply PC board on the SCU chassis.

What you should do:

1. To clear the error, click Clear error in the XYZ Display window.

To clear it using an RCU-II, press and hold down the Servo Power Off button and then press the Joy button twice.

2. Determine what caused the loss of power supply. If it was caused by a blown fuse, change the fuse.

3. If the error reoccurs, contact your Giddings & Lewis service representative.
